Does anyone know the fuel return line fitting size off the PT pump? Can I use the same size line as the feed for the return?

It's a SAE fitting into the pump. I think it's a 1/4" SAE. It has an o ring under it.

If you are replacing the lines with hydraulic line you want the smallest you can get for a return line. I.e. #4 jic fittings and quarter inch line. The smaller the return line the higher rail pressure you will have which = more power.
